In response to the defects of easy delamination, poor impact resistance, and low toughness in laminates, intra-layer aramid/glass hybrid weft-knitted reinforced composites without lamination were designed and prepared. This paper investigated the tensile, bending, and impact response of aramid/glass hybrid weft-knitted reinforced composites. Homogeneous and hybrid composites with glass: aramid hybrid ratios of 1:1, 2:1, 3:1, and hybrid modes of transverse hybrid, oblique hybrid, and vertical interlocking hybrid were prepared by vacuum resin transfer molding (VARTM) technique. The tensile and bending properties were evaluated from stress, modulus, and strain/deflection, and a scanning electron microscope (SEM) was employed. The impact response was analyzed from peak force, maximum displacement, and energy absorption. The results confirm that interlacing brittle glass yarns with aramid yarns exhibits a positive hybrid effect. The ratios of 50%, 33%, and 25% aramid fiber in the transverse hybrid enhanced the longitudinal strength by 72.86%, 52.13%, and 22.01%. The mechanical properties of the oblique hybrid are similar in warp and weft direction; by contrast, the other two hybrid methods demonstrate mechanical anisotropy. This article implements the preparation and mechanical properties research of non-laminated hybrid composites based on weft-knitted structures, which broadens the design and selection of prefabricated components for hybrid composites.

This study aims to develop composite laminates for the manufacture of prosthesis socket with enhanced mechanical performance. Layered hybridisation of fabrics (i.e. glass, carbon, and Kevlar fabrics) is used to manufacture hybrid composite laminates by resin infusion via vacuum bagging method. The response of these materials to compression loading is investigated by using compression-loading testes and the load-bearing ability was examined by tensile strength tests. Moreover, finite element analysis has been carried out by using the Abaqus software to predict the compressive failure load and damage failure modes for all sockets samples. Experimental results revealed that the hybrid laminates exhibited more stability and higher absorbing energy compared to non-hybrid laminates during compressive loading tests. Furthermore, the hybridisation of fabrics layers can play key role for improving the tensile strength properties of hybrid composite laminates compared to composite laminates without hybridisation. The numerical simulation results of compressive failure load and damage failure modes are in accordance with experimental results qualitatively as well as quantitatively.

Antibiotics released in the water pose a serious threat to human and ecological health. Therefore, it is of great importance to effectively remove antibiotics from wastewater. In this study, recyclable bacterial cellulose/sodium alginate/zeolitic imidazolate framework-8 (BC/SA/ZIF-8) aerogel composites were prepared by chemical cross-linking and in situ growth in freeze-drying. The successful preparation of the composite aerogel was confirmed by scanning electron microscope (SEM), Fourier Transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis. The results reveal that BC/SA/ZIF-8 aerogel composite has significantly high BET specific surface area of 165.24 m 2 /g than that of BC/SA at 7.39 m 2 /g. The BC/SA/ZIF-8 composite aerogel exhibited excellent adsorption performance for tetracycline hydrochloride, with a maximum adsorption capacity of 746.27 mg/g. The adsorption process followed the pseudo-second-order kinetic model and Langmuir adsorption isotherm model. Moreover, the reusability test on BC/SA/ZIF-8 composite aerogel revealed an insignificant decline in adsorption after six cycles. Therefore, BC/SA/ZIF-8 composite aerogel has a high potential as a novel and recyclable adsorbent for efficient removal of tetracycline hydrochloride from water.

Polyethylene terephthalate (PET) polyester fabric has been treated with different concentrations of sodium lignin sulphonate (SLS), a lignin based sustainable flame retarding agent. Treated PET fabric has exhibited different chemical loading on its surface varying from 15 to 60% depending on the concentration used. Treated fabric has shown 40–70% more limiting oxygen index (LOI) value as compared to the control PET fabric. 200 g/L SLS treated PET fabric (with 35% chemical loading) has shown LOI value of 27. In addition to it, melt dripping property of all the treated PET fabrics have been found to be stopped with lower shrinkage during combustion, as observed from the UL94 test results. TG analysis of the said fabric has shown 20–25% more char mass retention and lower rate of weight loss as compared to the control one. Char morphology of the control and the treated fabric has also been examined in different magnifications and analyzed in detail. Forced combustion test of the sodium ligno-sulphonate treated PET fabric has revealed 82% lower peak heat release rate (PHRR) as compared to the control PET fabric with less amount of carbon monoxide liberation during burning. Besides, a possible mechanism lies behind the flame retardancy of the SLS treated PET fabric also has been expressed and discussed scientifically.

In this study, a novel multifunctional carpet test device was proposed to overcome deficiencies of current technology, including manual operation error and fixed load. The newly developed test device can automatically perform short-term static loading, long-term static loading and thickness measurement on five samples, simultaneously. The application of the load is achieved by using pneumatic system elements and automation of the developed test device is obtained by a PLC (Programmable Logic Controller) software. The device was verified according to “trueness” and “precision” criteria via statistical analyses. As a result of trueness determination, the Mean Absolute Percentage Error (MAPE) values of the developed test device were between 0.001–0.023, in comparison to that of the traditional carpet thickness tester, which exhibits very close trend between two measurements. The precision analysis results revealed no significant difference in 95% confidence interval between developed test device and the carpet thickness tester. Moreover, the developed test device is capable for thickness loss test by brief moderate loading, prolonged heavy loading and carpet thickness measurement, following related international standards.

The urgent need for flexible strain sensors that are both aesthetic and functional is addressed, given the rapid development of smart wearable technology and the improvement of material level. To achieve this, silver-plated yarns based on nylon and nylon wrapped spandex were directly knitted into the sensor using cross-knit intarsia and plating technology. Five samples, with varying percentages of loops and tuck loops, were designed. The results indicated that the sensor demonstrated a GF of 2.80 kPa −1 at the Lx-axis and 3.67 kPa −1 at the Ly-axis, showing good repeatability during 1000 cycles of stretch/release. Moreover, it exhibited fast responsiveness, enabling it to discriminate between different rates of stretch. The sensor's potential for application in wearable smart medical monitoring was demonstrated by its ability to be embedded in garments for joint motion monitoring. These findings collectively suggest that the designed knitted strain sensor holds promising potential for use in the field of wearable smart medical monitoring.

This study deals with the prediction of the mechanical properties of wool bundle fibers and the characterization of the fracture performance of fiber fracture sound. Acoustic emission detection was used to record the fracture sound of wool fibers. According to the fracture sounds, the tensile properties of the bundle fibers were obtained. Acoustic emission provided a convenient method for obtaining fibers breaking elongation distribution. Based on the fiber bundle model and fiber breaking distribution, the fracture strength and elongation of bundle fibers could be predicted. Meanwhile, based on the correlation between the amplitude of fiber fracture sound and fiber breaking strength, the single fiber breaking strength could be predicted and the tensile properties of bundle fibers could also be obtained. The prediction results based on bundle fiber fracture sound were more similar to the measured results. Besides, the number of fibers within the bundle increased, the fiber interaction was also enhanced, and the bundle fiber strength prediction results were affected. This work was considered to have the potential of being used in the prediction of mechanical properties of natural fiber composites.

The pollution caused by petroleum-based waste has motivated the development of ecologically friendly bio-based materials. Natural fibers are becoming increasingly popular as a renewable and biodegradable resource. In this study, we prepared a kapok/waste silk nonwoven (KSN) by wet-laid and hot-pressing, which had adequate mechanical strength, hydrophilic, lipophilic, and biodegradable properties. The effects of the kapok fiber proportion on the morphology, air permeability, softness, mechanical property, wettability, and biodegradability of KSN were studied. The results demonstrated that the thickness, porosity, air permeability, and softness decreased as the proportion of kapok fiber increased. The mechanical property was significantly enhanced, and the breaking strength increased from 0.58 MPa to 10.85 MPa. With the increase in the proportion of kapok fiber, the spreading time of oil and water increased and decreased respectively, and the static contact angles were below 50°. Degradation rate improved with the increase of kapok fiber proportion, with a maximum degradation rate of 49.41% (30 days). Therefore, the multifunctional, low-cost, easily prepared, and biodegradable kapok/waste silk nonwovens is a promising bio-based material with superior application prospects in dressings, facial mask substrate, packaging, and related fields.

This paper investigates the quasi-static mechanical properties and damage behavior of flexible composites prepared from high-performance glass fiber-based multi-axial warp knitted fabrics as reinforcement and high tenacity environmentally friendly thermoplastic polyurethane as a matrix. The composites were produced by attaching thermoplastic polyurethane (TPU) to the top and bottom of the fabric using a vulcanization machine, followed by hot-pressing for different temperatures and time settings. Moreover, the effects of different preparation processes on the tensile strength, static puncture resistance, and tear strength of flexible composites were investigated in this paper. The results indicated that both hot-pressing temperature and vulcanization time had a significant impact on the mechanical properties of the composites. With an optimum vulcanization temperature of 185°C and a vulcanization time of 10 min, the composite provides optimum tensile strength and puncture resistance. Tear strength is the worst and is related to the reinforcement’s organisational structure and the interfacial bond’s strength. The results of this study are of theoretical and practical significance for applying high-performance multi-axial warp-knitted flexible composites as raw materials in the construction field.

The functional fabric with high electromagnetic shielding (EMI) performance, durability as well as good handle has been drawing increasing attention. Herein, AgNPs@MXene of high conductivity was prepared by in-situ reduction of AgNO3 onto MXene. Then, boron-enhanced AgNPs@MXene-PDA coating fabric (BAMP-F) of high properties was fabricated through polydopamine (PDA) coating, AgNPs@MXene assembly, and finally sodium tetraborate (Na2B4O7) densification. Results showed that the surface resistivity of AgNPs@MXene arrived at 7.22 × 10−4 Ω·m and decreased by one order in comparison with pure MXene. After 0.6 mol/L PDA coating, AgNPs@MXene deposition for 6 times, and 0.02 mol/L Na2B4O7 densification, the surface resistivity of BAMP-F reached 7.08 × 10−3 Ω·m and its EMI values of one layer attained 34.51 dB. Compared with AgNPs@MXene-PDA coating fabric (AMP-F), the electrical conductivity of BAMP-F improved by 47.6 % and its electromagnetic shielding performance increased by 42.8 %. BAMP-F possessed good handle and maintained excellent EMI performance after bending for 600 times, washing for 60 min, and tearing.

Herein, AgNPs@MXene of high conductivity was prepared by in-situ reduction of AgNO3 onto MXene. Then, boron-enhanced AgNPs@MXene-PDA coating fabric (BAMP-F) of high properties was fabricated through polydopamine (PDA) coating, AgNPs@MXene assembly, and finally sodium tetraborate (Na2B4O7) densification. Results showed that the surface resistivity of AgNPs@MXene arrived at 7.22 × 10−4 Ω·m and decreased by one order in comparison with pure MXene. After 0.6 mol/L PDA coating, AgNPs@MXene deposition for 6 times, and 0.02 mol/L Na2B4O7 densification, the surface resistivity of BAMP-F reached 7.08 × 10−3 Ω·m and its EMI values of one layer attained 34.51 dB.
